Wathai 120mm x 32mm 12V High Airflow DC Brushless Blower Fan for Radiator, Desktops, Gaming Consoles, TVs, Routers, Computers

The media could not be loaded. This is a high quality fan. I am trying this style and another style to exhaust the warm air from my closed in shelf / 3-sided-box in a walk-in closet that I use as my wiring closet for Wi-Fi, home network, NAS and security video recorder.It is a solid fan but has three hardware shortcomings that the manufacturer should be correcting:1) the screw holes on the 'back' side of the fan intended to mount the grill are NOT COUNTERSUNK despite the provided screws being intended for countersunk holes. It is ironic that the holes right next to them to mount this fan in a chassis are countersunk.2) There are only two screws provided (although the instruction sheet says four), so it is presumed they are for the grill. That said, those screws are too long and project beyond the grill in what could be a dangerous length to catch skin depending on where the fan is mounted. So, I just took some simple SHEET METAL SCREWS I had on hand and screwed the grill directly to the housing.3) Numerous buyers rightly complain that the thin wiring to the fan has no strain relief and could be torn free, particularly in the applications where it says this could be a blower for a BBQ or fireplace. I SOLVED that by applying a self-adhesive wire dressing clips I had on hand plus a the twist tie that was on the fan's cord.Looking forward to finding the right combination of (variable) fan speed and noise to exhaust the desired amount of heat.

Works good. No problems

The Fan:So far so good. It has maybe 72hrs on it so far recirculating 65C air. I worry about the electronics... but so far it's holding up well. It does not move as much air as some other models, but I knew that when I bought it. For my use, it's plenty good enough.The cord:Throw it away. Or fix it. The switch on this cord is a fire hazard. The wire is poorly crimped and I was able to pull the wire out of the contacts inside the switch. The switch makes kind of intermittent contact when in the ON position... which creates a high resistivity connection... which makes heat... which melted part of the switch. Thankfully I was in the room when the device turned off spontaneously to diagnose why and noticed that the switch was hot. DO NOT USE THIS SWITCH. Or do. It's your choice and I'm not your mom.

Arrived the next day, really solid build, and will hopefully last a while. I’ll definitely buy another one if I need it.

This blower is exactly what I was expecting and works great. The airflow is about half of a standard hairdryer but much quieter. My use case is a little different from most folks so I aded some pictures. I wanted the ability to do timelapse pictures during storms and there are solutions out there for keeping the rain off the lens during a storm but they are anywhere from $1,000 to $15,000 and I figured I could get 80% there for $20. So I already had a plexiglass shield for my camera and I just mounted this fan on the underside of the shield and it works great blowing the rain out of the way so drops don't land on the lens. Actually works pretty well and I love the variable remote that come with it. It made the whole DIY installation a snap.

Works great for car audio.I cut the wire fitting off at the end of the wire- to connect it to the ground and the remote wire inlets.Fans turn on when I turn the key. Both fans keep my amp from overheating, even in the Arizona triple digits°.Very effective, not noisy at all.I definitely recommend for the car audio enthusiast. It works.

This fan will not run at any voltage less than 11.5. I'm seriously disappointed with this. I have it connected to a potentiometer and I can't even bring it off full speed without it shutting off.I measured the voltage coming off the terminals to the fan and once it hits 11.5 the fan shuts off. This is connected directly to a 12v battery for testing purposes. I wanted a fan I could adjust from 5-9-12 volts to adjust accordingly to a thermostat. Guess that isn't happening. Couldn't adjust the voltage to this fan and now it has started vibrating terribly. I would return it except I hacked the power leads for my own needs. Save your 15 bucks and find another fan. This thing is garbage and only worked for about a week.

The fan makes a lot of noise when running at 12 volts. I reduced the voltage to 5 volts and the noise is much less but i don’t get the volume of air i wanted.
